Mr. J. P. Mack Mr. A. M. Polger A-*****' Regarding survey of wastage of water at Las Vegas: I want everyone concerned to know the facts as found. We checked 7310 homes which had coolers. Of these there were 4934 with pumps and 2376 without pumps and floats. Now the question arises, are the pumps and float valves in these 4934 locations in good condition when put in operation. This will have to be Cheeked on final survey when coolers are placed in operation. This does not include the large evaporating coolers in the hotels and numerous clubs. With bad order float valves and overflow pipes in pans not properly placed, there could be a large amount of wastage of water going to sewer. Now, we have the 201 refrigerating ice box units which are running water to sewer 24 hours per day at five gallons per minute. Many of these units are connected directly to sewer pipes inside the building which is a cross connection. We found some markets which have two 3/8" copper tubes going directly into toilet bowls and in many locations we found 1/4"- 3/8"- 1/2"- 3/4" cooling water from condensers connected to cleanout plugs of sewer drains in building. Imagine what will take place if water is shut off in main outside. The vacuum will draw this sewerage into culinary line, just what we call a cross connection. Los Angeles, March 6, 1950 20-334-1
